Benefits of technology

The present patent is about an improved actuation device for well tools. The device allows for better control of the setting diameter and force of the tools, which are currently hydraulically actuated. The new device can be adjusted to different well tools and can be used in various well operations. The device includes a tubular housing with key slots and keys that can be used to control the movement of the device. The device also includes a threaded shaft that can be rotated to deploy or retract the tool. Overall, the new device provides better control and flexibility for well tools.

Problems solved by technology

Such hydraulically actuated devices (e.g., hydraulic setting tools) do not allow the user to control setting diameter or force.

Embodiment Construction

[0017]Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of an actuation device in accordance with the disclosure is shown in FIG. 1A and is designated generally by reference character 100. Other embodiments and / or aspects of this disclosure are shown in FIGS. 1B-4. The systems and methods described herein can be used to control actuation and deployment of one or more mechanical features of a well tool (e.g., an anchor).

[0018]Referring to FIGS. 1A and 1D, an actuation device 100 for one or more well operations is shown in a retracted state (e.g., FIG. 1A) and a deployed or at least partially deployed state (e.g., FIG. 1D). The actuation device 100 can include a tubular housing or body 101 having a plurality of key slots 101a that can receive a plurality of keys 107. As shown, the tub...

Abstract

An actuation device for well operations can include a tubular body including a plurality of key slots, a threaded shaft disposed within the tubular body that rotates relative to the tubular body and is fixed axially relative to the tubular body, an actuator disposed within the tubular member that moves axially relative to the tubular body, wherein the actuator includes a ramp portion and a threaded neck portion that engages with the threaded shaft such that when the threaded shaft rotates, the actuator moves axially relative to the tubular body, and a plurality of keys, each disposed in one of the plurality of key slots and in operative communication with the ramp portion such that as the actuator moves axially relative to the tubular body, each key is urged radially outwardly from the tubular body.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a National Phase Application under 35 U.S.C. § 371 of PCT International Application No. PCT / US2015 / 067874, filed Dec. 29, 2015, the entire contents of which are hereby incorporated by reference herein in their entirety.BACKGROUND1. Field[0002]The present disclosure relates to wells, more specifically to actuation devices for well tools.2. Description of Related Art[0003]Certain devices for use in wells are actuated hydraulically. Such hydraulically actuated devices (e.g., hydraulic setting tools) do not allow the user to control setting diameter or force. The hydraulic tools are either fully deployed or fully retracted or transitioning from one position to the other.[0004]Such conventional methods and systems have generally been considered satisfactory for their intended purpose. However, there is still a need in the art for improved actuation devices for well tools. The present disclosure provides a solution for this ...
